Heegaard Floer homologies and cuspidal curves in CP^2
Using the inequalities for correction terms in Heegaard Floer theory we
show constraints for singularities that can occur on a plane rational
cuspidal curve. In particular we prove a conjecture by Fernandez de
Bobadilla, Luengo, Melle--Hernandez and Nemethi.
Generalizations apply for curves of higher genus.
